Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed May 10, 1915. Serial No. 27,129.

T 0 all whom it may concern Be it known that I, LYNroRD O. GREEN, acitizen of the United States, residing at Capay, in the county of Yolo,State of California, have invented certain new and useful Improvementsin Music-Leaf Turners; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in music leaf turners.

One object of the invention is to provide a simple device of thischaracter which can be readily applied to the music ledge of a piano orto a music stand.

Another object is to provide simple and novel means for turning themusic leaf and releasable means for holding the leaf turning means.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.

In the drawing: Figure 1 is a front elevation of a music leaf turnermade in accordance with my invention, Fig. 2 is a side elevation, Fig. 3is a vertical section on the line 33 of Fig. 1, and Fig. 4 is anenlarged detail perspective view of the detent.

Referring particularly to the accompanying drawing, 10 represents asuitable box which is provided with a clamp 11 having set screws 11 forattaching the box to the music shelf or ledge of a piano, organ, musicstand or the like. Extending vertically through the box is a post 12,the lower portion of which is provided with a laterally extending pin 13which projects through the slot 14 formed in the front of the box.Slidably mounted on one end of the box is a beveled ended bolt 15, theother end of which is pivotally connected to one arm of a bell cranklever 16. Pivotally connected to the end of the other arm of the bellcrank is a stem 17 which carries on its other end a button 18. A coilspring 19 is wound around the post 12 below the arm 13 and has one ofits ends secured to the arm and the other end to a box. This spring isso wound that when the arm 13 is swung to the right the spring will beunder tension with a tendency to move the arm to the other side of thebox. A coil spring 20 is mounted on the stem 17 between the crank arm,and the button. When the arm 13 is swung over to the right it engagesthe beveled end of the bolt 15 pushing the same back until the arm ispassed and then snapping outward to hold the arm against movement. Thenupon pressing on the button 18 the bolt will be withdrawn and releasethe arm 13 permitting the same to be thrown around to the left with thepost 12 under the influence of the spring 19. In the upper end of thepost 12 is the laterally extending arm 21 carrying on its outer end leafengaging means 22 for engagement with the music sheet to be turned. Itwill also be seen that when the arm 13 is turned to the right by takinghold of said arm with the fingers and engaged with the detent that thearm 21 will turn with the post in such position that the leaf to beturned can be engaged with the clips, and that upon release of the arm13 the arm 21 will be thrown to the left carrying the music leaf withit.

What is claimed is:

A music leaf turner comprising a box having means for attaching the sameto a support, the front of the box having a transverse slot formedtherein, a vertically slidable bolt mounted within the box, on one endthereof, and projecting across one end of the slot, an operating stemslidably extending through the front of the box, a bell crank leverpivoted at its angle to said end of the box and having its armsconnected respectively to the bolt and stem, a vertical post mounted inthe box and carrying leaf engaging means on its upper end, a springmounted on the post within the box, and, a laterally extending armcarried by the post and extending through the slot, said arm beingarranged to be moved along the slot into engagement with the said boltagainst the action of the spring, the spring having one end connected tothe arm and the other end connected to the box.

In testimony whereof, I affix my signature, in the presence of twowitnesses.
